Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742270, here are decompositions:

7 + 8742263 = 8742270
11 + 8742259 = 8742270
73 + 8742197 = 8742270
83 + 8742187 = 8742270
101 + 8742169 = 8742270
109 + 8742161 = 8742270
113 + 8742157 = 8742270
137 + 8742133 = 8742270

Showing the first eight; more decompositions exist.
